Hadoop-based startup Cloudera raises $40M from Ignition Partners, Accel, Greylock

Cloudera provides its own take on Hadoop’s powerful open-source data management software and couples it with IT support and management. Using Hadoop, enterprises can store and process huge amounts of unstructured data. But Hadoop can often be unwieldy and difficult to manage, so Cloudera helps make it possible to manage that data effectively.
